✨ Highlights

• Expanded Midnight state queries so large unspent output lists can be read page by page.

• Broadened Midnight data access so governance, network settings, block, epoch, and status details are easier to retrieve.

• Filled Blockfrost block responses with summary and header details so applications receive more complete block data.

• Completed Blockfrost address and transaction output responses with missing data and reference details so downstream tools can resolve richer output information.

• Corrected live stake totals in pool queries so reported stake values stay accurate.

• Logged rollback cleanup failures for stored data so operators can spot incomplete cleanup sooner.

• Calculated slots across Byron history so chain position handling remains correct for older blocks.

• Applied epoch transition effects to pools and governance in Leios so network state stays consistent.

• Restored Dijkstra block creation so the node follows expected chain rules.

• Tightened incoming block checks so Dingo rejects malformed or out of order blocks earlier when validation is enabled.

🧪 Testing, Docs, and Tooling

• Strengthened Midnight rollback coverage so rollback paths without recorded events stay verified.

• Documented the previous release across the supported published languages so the release history stays current.
